.IMPRQVEMENT IN PLiERs..

Specification forming part of Letters Patent No. 181,175-, datedAugustl, 1876; application led 'June 3, 1876. v

T0 all whom it may concern: l

Be it known that I, WILLIAM P. HUNTooN, of Stuart, in the county ofGuthrie and State of Iowa, have invented an Improved Pliers forWatchmakers and Jewelers Use, ot' which the following is aspecification:

` The object ot' my invention is to provide a" tool that can beadvantageously used as a pliers, and also as a vise in removing, tting,and handling-watch-hands and other small parts of delicate machinery. Itconsistsin forming vertical, and longitudinal intersectintersectingandcrossing the vertical grooves.

c b c. The grooves a. b are smallest at the bottom, and iiare andenlarge toward the top, as required, for the free passage ofbroachingtools. These vertical grooves vary in size, and a graduatedseries, varying in number, may be uniform in each jaw. y

'Ihe groove c is straight and uniform in size from top to bottom, asrequired, to gripe and hold pins, screws, and similarl small andstraight parts. A graduated series of these straight vertical groovesare designed to be formed in each jaw between the Haring grooves. c

These grooves and cavities a b c d may be formed by milling, or byvmeans of dies, or in any suitable way that well-tempered grooved jawscan be produced. v

Ihe size of the pliers and their jaws and grooves mayvary, as desired.

In the practical operation and test of Athe utility of my invention,take the pliers in the hand and open the jaws to admit the disk orflange of the hour or minute hand of a watch into the longitudinalgroove d intersecting the vertical groove a, and then close the jaws.

By thus using my combination-tool as a pliers, you can readily seize andremove or pick up a watch-hand, and then retain it, as in a vise, tobroach and tit it to its post, by simplyturning your hand and invertingthe jaws and the watch-hand. While thus inverted you can pass a taperingtile, or any suitable broaching-tool, through the watch-hand to enit iniiling and fitting it in its place on the` post.

The second-hand of a watch can be readily manipulated in the same mannerby means of the smallerv groove b and its intersecting groove d.

J ewel-plates, ratohets, collets, and similarsmall perforated parts ot'delicate machinery can be advantageously manipulated in a similar mannerby means ot my improved tool.

I ,fam aware that pinchers and jaw-tools have been bent, and theirjawsserrated and grooved; but I claim that my manner ofl intcrsecting atright angles a series of Haring or conical vertical grooves withcouoidal longi-Y tudinal cavities or grooves in the jaws of bent pliers,to adapt them for the alternate and simultaneous uses of a pliers andvise, is novel and greatly advantageous.

I am also aware that straight vertical g grooves are common injaw-toolsl for holding pins, screws, Snc.; but I claim that mytool,having a series of intersecting grooves, a d, for handling and holdingperforated and diskform articles, and also a series of straight verticalintervening grooves -for hand ling and UNITED Sir-Aras PATENT.substantially as and for 'the and described. 2. As a newcombination-too1, the bent pli- Awholdingf straight pins and similarsmall objects, is a new and convenient combinationtool.

I claim as my invention- 1. In bent pliers, the vertical andhr-zlonicalfgrooves or cavities a b, intersected by the longitudinal and colloidalgrooves or cavitiesd d; purposes shown ers, havingA a graduated "seriesof intersecting* grooves, a, d and b d, and also a l graduated' seriesof vertical straight grooves, 0, substantially as and for the purposesshown and described.
